Contact systems

We make high demands on the metal contact surfaces in order to protect connectors against corrosion and environmental influences.
Naturally, we use only high-grade copper alloys and Cr(VI)-free processed steel parts.

Tin-plated contact system

Tin-plated metal part

Tin-plated contact systems are a practical and inexpensive solution for soldering applications.

Tin initiates an intermetallic reaction with base materials, such as brass or bronze. This can lead to increased corrosion. A nickel resistive layer is used in Phoenix Contact products to prevent this reaction.
